- Fixed Azure accounts timeout issue when there is no out-bound IP ([#74191](https://github.com/kubernetes/kubernetes/pull/74191), [@andyzhangx](https://github.com/andyzhangx))
- Fixed Azure Container Registry anonymous repo image pull error ([#74715](https://github.com/kubernetes/kubernetes/pull/74715), [@andyzhangx](https://github.com/andyzhangx))

- The `generate_groups.sh` and `generate_internal_groups.sh` scripts from the `k8s.io/code-generator` repo are deprecated (but still work) in favor of `kube_codegen.sh` in that same repo.  Projects which use the old scripts are encouraged to look at adopting the new one.

* vSphere Cloud Provider supports VMs provisioned on vSphere v6.5. ([#59519](https://github.com/kubernetes/kubernetes/pull/59519), [@abrarshivani](https://github.com/abrarshivani))

* Created k8s.gcr.io image repo alias to pull images from the closest regional repo. Replaces gcr.io/google_containers. ([#57824](https://github.com/kubernetes/kubernetes/pull/57824), [@thockin](https://github.com/thockin))

- Update Golang to v1.13.14
  - Update bazel to 2.2.0
  - Update repo-infra to 0.0.8 (to support go1.14.6 and go1.13.14)
    - Includes:
      - bazelbuild/bazel-toolchains@3.4.0

* Deprecate auto detecting cloud providers in kubelet. Auto detecting cloud providers go against the initiative for out-of-tree cloud providers as we'll now depend on cAdvisor integrations with cloud providers instead of the core repo. In the near future, `--cloud-provider` for kubelet will either be an empty string or `external`.
